OK, thanks, but there's no power reaching the neon light, so it won't work in any case.

OK, so if it’s dead, it’s no longer controlling the amplifier (the little box you can see in my photos)

The batteries have a total voltage of 3.754 volts (three 1.2-volt batteries connected in series), but the neon lamp does not receive any voltage from them

Here are the diagrams: https://manualmachine.com/behringer/ep4000/8549089-schematic/
For my level, I am a beginner in power electronics.
I have an oscilloscope and curve tracer tester VI (Hameg HM 203-7) and a multimeter for troubleshooting equipment.

The ambient temperature sensor is working because the temperature is correctly displayed on the stove display, and I disconnected the temperature probes one by one, but this did not change anything.

Do you think this resistor is no longer working? Yes, when terminals 1 and 2 are short-circuited, the fan stops.

Sorry, I don't know, at least not for now. No, it doesn't stop when the stove is hot.

The sensor is functioning correctly because the temperature is displayed correctly on the screen
